str_wrap: Wrap words into nicely formatted paragraphs

In stringr: Simple, Consistent Wrappers for Common String Operations

Wrap words into nicely formatted paragraphs

Description

Wrap words into paragraphs, minimizing the "raggedness" of the lines (i.e. the variation in length line) using the Knuth-Plass algorithm.

Usage

str_wrap(string, width = 80, indent = 0, exdent = 0, whitespace_only = TRUE)

Arguments

string	Input vector. Either a character vector, or something coercible to one.
width	Positive integer giving target line width (in number of characters). A width less than or equal to 1 will put each word on its own line.
indent, exdent	A non-negative integer giving the indent for the first line (indent) and all subsequent lines (exdent).
whitespace_only	A boolean. If TRUE (the default) wrapping will only occur at whitespace. If FALSE, can break on any non-word character (e.g. /, -).

Value

A character vector the same length as string.

Examples

thanks_path <- file.path(R.home("doc"), "THANKS")
thanks <- str_c(readLines(thanks_path), collapse = "\n")
thanks <- word(thanks, 1, 3, fixed("\n\n"))
cat(str_wrap(thanks), "\n")
cat(str_wrap(thanks, width = 40), "\n")
cat(str_wrap(thanks, width = 60, indent = 2), "\n")
cat(str_wrap(thanks, width = 60, exdent = 2), "\n")
cat(str_wrap(thanks, width = 0, exdent = 2), "\n")
